Ingredients

  • 2 cups flour
  • 2 cups granulated sugar
  • 3/4 cup unsweetened cocoa powder
  • 1 teaspoon baking powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3 large eggs
  • 1 cup milk
  • 1 cup hot water or hot coffee
  • 1/2 cup vegetable oil
  • 2 teaspoons vanilla extract
  • 3 cups mini marshmallows
  • 1/2 cup butter
  • 1/4 cup cocoa powder
  • 1/3 cup milk
  • 2 cups powdered sugar
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat oven to 350°F (175°C) and grease a 23×33 cm baking pan.
  2. In a large bowl, whisk together flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt.
  3. Add eggs, milk, vegetable oil, and vanilla extract. Mix until smooth.
  4. Pour in the hot water or coffee and mix on low speed. Batter will be thin.
  5. Pour batter into the prepared pan and bake for 30–35 minutes, or until a toothpick comes out clean.
  6. Immediately sprinkle marshmallows evenly over the hot cake. Let them soften for 5 minutes.
  7. In a saucepan, melt butter over medium heat. Stir in cocoa powder and milk and cook for 1 minute.
  8. Remove from heat and whisk in powdered sugar and vanilla extract until smooth.
  9. Drizzle warm chocolate mud sauce over softened marshmallows and let it soak into the cake.
  10. Allow to rest for 20–30 minutes before slicing and serving.

Notes

  • Use coffee instead of water to enhance the chocolate flavor.
  • Add chopped nuts between the marshmallow and sauce layer for crunch.
  • This cake is even better the next day once the sauce sets into the crumb.
  • Store covered at room temperature or refrigerate for a longer shelf life.
  • Reheat slices in the microwave for 10–15 seconds for a gooey texture.
